変化する：

<div style="text-align:center; color: #4E1329; font-size: smaller; float:none">
    you can search by acc no and username
</div>

に

<div style="width: 100%; text-align:center; color: #4E1329; font-size: smaller; display:inline;">
    you can search by acc no and username
</div>

注：インラインスタイルではなく、CSSクラスの使用を検討することもできます。

編集：編集内容を確認したら、クラスblockで幅を設定する必要があります。テキストを中央に配置できるようにするには、幅を100％にする必要があります。100％の幅が機能するためには、幅のある親が必要です。ブロックに幅がある場合は、CSSを投稿してください。

編集-最終改訂：

display:inline今それを混乱させています。これとfloat:none;削除する必要があります。

<div style="width: 100%; text-align:center; color: #4E1329; font-size: smaller;">
    you can search by acc no and username
</div>

両方の div は別々で、上の div にはパディングがあります。以下のdivにもパディングを追加してみてください

style ="padding: 12px 13px 0px 12px;text-align:center;"

これがうまくいくことを願っています。

あなたの Div には 1 つのインライン CSS があり、あなたの div はdisplay:inline. これは何か特別な理由がありますか？同じものを削除すると、Divが中央揃えになることがわかります。

周囲のdivと関係があるようです。固定の with でその周りに div を配置すると、すべて問題ないように見えます。

HTML:

<div style="width: 300px; border: 1px solid red;">
    <div style="padding: 12px 13px 0px 12px;">
        <span class="label">Search :</span>
        <input name="ctl00$MainContentPlaceHolder$txtSearch" type="text" id="MainContentPlaceHolder_txtSearch" class="textbox" Size="16" />
        <input type="submit" name="ctl00$MainContentPlaceHolder$btnSearch" value="Search" id="MainContentPlaceHolder_btnSearch" class="button" style="float: right" />
    </div>
    <div style="text-align:center; color: #4E1329; font-size: smaller; float:none">
        you can search by acc no and username
    </div>
</div>
